ATTOR/VEI UN ITE ATENT FICE" MOTOR FOR OPERATING SWINGING DEVICES.

SPECIFICATION forming part of Letters Patent No. 404,613, dated June 4, 1889.

Application filed March 15, 1889.

To all whom it may concern.-

Be it known that 1, CHARLES J. B. GAUME, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Motors for Operating Swinging Devices, of which the following is a full, clear, and exact description.

This invention consists in a clock-work-escapement mechanism of special construction, including a novel escapement device, for operating swinging cradles, couches, hospitalcots, and other like structures, substantially as hereinafter described and pointed out in the claim,whereby power is economized, noise avoided, and heavy bodies may be kept in swinging motion for a prolonged period.

For the convenience of description, the invention will here be shown and described as applied to a longitudinally-swinging cradle; but it is equally applicable to cradles which swing in a crosswise direction, to swinging couches of various kinds, hospital-cots, and other swinging structures. The 1ongitudinally-swinging cradle here shown therefore forms no part of this invention, other than it represents a swinging structure to which my improved operating mechanism is applied.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents. a side elevation of a longitudinally-swinging cradle and its framework with my invention applied. Fig. 2 is an end elevation of the same; Fig. 3, a longitudinal section in part upon a larger scale on the line so 00 in Fig. 2; and Fig. 4, a plan view of the mainspring of the clock mechanism, with ratchet, pawl, and main driving-wheel.

A A indicate the posts of the fixed frame, within which the cot portion B of the longitudinally-swin ging cradle is arranged to move, said cot portion being carried by cranked rods 0 C at its opposite ends fitted to turn at their upper or trunnion ends in the posts AA.

D indicates the main or operating spring of the clock mechanism, attached at its one end to a frame E, secured to the stationary frame of the swinging structure, and at its other end to the rotating arbor 1), fast on which is a ratchet-wheel c, that a pawl d, fast to a main driving-wheel F, which is loose on the Serial No. 303,478. (No model.)

arbor b, engages with, as in other spring clock mechanism. The main driving-wheel F is a chain or sprocket wheel with which an endless chain G engages, and serves to drive a train of any numberof sprocket or chain pinions and wheels H I J and K K through connecting-chains G. The last pinion J of this train, which is loose on its arbor, constitutes the escapement-wheel of the clock mechanism, and has a series of pins 6 on one side or face, by which, through suitable devices, as hereinafter described, and which differ from an ordinary pallet, the swinging motion of the cradle is controlled,,the swinging cradle or structure, with the weight of the person with which it is loaded,virtually forming the pendulum of the clock mechanism. By using chain wheels and pinions and chains for the operating train of the clock mechanism noise, so obj ectionable to swinging cradles and other like structures, is avoided.

The devices by which the escapement-wheel J is controlled and the proper action given to the swinging structure consist of a stop-pawl M and a releasing-lever N, pivoted, respectively, as at f g, to a fixed upright L, which may be on the inside of one of the posts A. The stop-pawl M is controlled by a spring h, which operates to throw its lower or shoe end 2' in toward the pins 6 on the escapementwheel to intermittently stop said wheel, but not with any sudden shock, noise, or jar, as the shoe end 2' of said stop-pawl is made concave on its face for each pin e in succession to freely work under till gradually arrested by the nose end of said shoe, as shown in Fig. 3. This stop-pawl is intermittently released from its hold on the escapement-wheel by the separate releasing-lever N, to keep up the inter mittent action of the escapement-wheel and swinging movement in reverse directions successively of the cradle or swinging structure with which said lever is connected. Thus said lever N, which is forked at its upper end for the purpose, engages with a pin Z on an arm of one of the cranked rods C, or it might be onany other suitable part of the swinging structure, so as to vibrate in common with the latter, which it serves to drive or swing in the one direction by the action of the escapement-wheel J when the pins 6 are free from being held by the stop-pawl M. The foot part IOC m of the lever N is suitably beveled, as at 42., where each pin 6 in succession of the escapement-whcel comes in Contact with it to drive or swing the cradle in one direction, thus giving an easy and almost noiseless sliding motion to said pin on the foot-piece WI. The stop-pawl M will then have returned by the action of the spring 72 to its normal position to arrest the escapc1nentwheel by its next succeeding pin e, and until the cradle and lever N in swinging back effect its release for repeating the driving action of the escapemcnt-wheel upon said lever.

To give a noiseless and easy release to the stop-pawl M, the lower arm of the lever N is provided on its inner side with a soft cushion or pad 5, made of leather or other suitable flexible and noiseless material, that as the lever N is swung inward comes in contact with the stop-pawl M and temporarily moves the latter from its engagement with the escapemcnt-wheel, as required.

This escapement mechanism is not limited to work light swinging bodies, but will work even betterwith heavy than light ones, opcrates with but little power, and is almost, it not quite, noiseless in its action.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In cloclcwork-escapement mechanism for actuating swinging cradles and other swinging structures, the combination, with the escapement-wheel. J, provided with a series of pins (2,013 the stop-pawl M, controlled by a spring and having a concave shoe 1', adapted to successively engage with said pins, and the releasing-lever N, adapted to operate the swinging structure, and having a shoe m for operation by the escape]nent-wheel, and a set t cushion or pad .5, operatingto release the stop pawl from the cseapement-wheel, essentially as shown and described.
